Hey everyone, thanks in advance for your help! Two or three weeks ago I purchased a Seagate Momentus 500GB 7200rpm hard drive from Best Buy. Since then I have had my MacBook freeze on me 3 times, before I replaced my HD it had never froze on me before, that I can remember. Today I get home from work, and go to enter my password to get the screen saver to go off and BOOM there is goes, its frozen. So I held the power button to get it to turn off and let it sit for about 5 secs. Turn it back on, grey screen...it did make the "Chime" sound though. Hold the power button again to turn it off, I let it sit about a min. and tried to turn it on again. Same thing, I hear the chime, and then just the gray screen. I let it sit on the gray screen for a min and then a folder appears flashing at me with a question mark in the middle. My HD is dead isnt it!? Nothing else has changed, not the ram or anything. My MacBook specs are in my signature. Thanks again for your help!!!
